Short summary

We reveal for the first time the global variations of PAHs and derivatives in marine air. We found that marine aerosols in East China Sea (ECS) and Western Pacific (WP) were significantly affected by coal and engine combustion, while those in Bismarck Sea (BS) and East Australian Sea (EAS) were mainly influenced by wildfire and coal combustion. The Antarctic Ocean (AO) was dominated by biomass burning and local shipping emissions. This finding helps elucidate the mechanism of the global PAH cycle.
